We find the real cause of the problem and put it right, backed by 10–20 year guarantees which can be insurance-backed through GPI.

Keeping your property protected.
Customers often worry about what happens to their home while remedial work is going on. We understand, and we do not take this part of the job lightly.
Once contracted to carry out remedial works, the first step we take is planning how to protect your furnishings and flooring. Many years of experience have taught us how important this is to you, the customer, so it is treated as part of the job, not an afterthought.
We ask for the areas we will work in to be cleared as best as possible. Any furnishing left in the rooms is covered with plastic sheeting, and floors are covered with sheets of heavier-duty Proplex protection board plus further layers of plastic sheeting. When the work is finished, the rooms are handed back clean.
- Furniture covered with plastic sheeting
- Floors protected with heavy-duty Proplex boards and layered sheeting
- Rooms left clean, replastered and ready to decorate
“We do not find problems that do not exist.”
Not all damp is rising damp. Much of it is condensation from everyday moisture and poor ventilation. Our founder Joe is PCA trained, and whoever surveys your property is one of the operatives who does the work. The job is to find the real problem, then specify the right remedial work. If nothing needs doing, the report says so.
How we workThe damp and timber problems we diagnose and fix.
Seven services, and every one starts with a proper diagnosis. Completed work carries a guarantee of 10 to 20 years, which can be insurance-backed through GPI.
Find out what's behind the walls before you exchange.
A pre-purchase damp & timber survey checks the walls, floors and timbers of the house you're buying. The written report reaches you within 48 hours.
Mortgage valuations barely look at damp or timber, and when a homebuyer report spots something, it usually just says "refer to a specialist". We are that specialist. We inspect the property for rising and penetrating damp, condensation, rot and woodworm, and send you a written report with real costs and photographs within 48 hours, before you exchange.
- Clear written report: what we found, the cause, and what fixing it costs
- Many buyers use the report to renegotiate the purchase price
- If nothing needs doing, the report says exactly that
- Remedial work backed by GPI insurance-backed guarantees, accepted by UK lenders
